Hatshy [7]

Hello,

Answer:

x = 13

Step-by-step explanation:

    7x + 5 + 5x + 19 = 180

⇔ 12x + 24 = 180

⇔ 12x = 180 - 24

⇔ 12x = 156

⇔ x = 156/12

A video sharing website starts with 20,000 members. Each year it loses 25% of the members, but adds 10,000 new members after the
MrMuchimi
20,000 x 25 = 500,000
500,000 divided by 100 = 5,000 members are lost.
Members left = 15,000
Members added = 10,000
Members every year  = Members left + Members added
                                   =          15,000 +  10,000
                                   =          25,000

m_a_m_a [10]

Answer:

$2.5

Step-by-step explanation:

Number of pounds of banana needed = 5 pounds

Cost per pound of banana = 0.50

To solve using place value blocks :

Ignoring the decimal in the cost per pound:

We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.

5 * 5 = $25

Now we can add the one decimal point (in the cost per pound) to our result

Then we have $2.5

Hence, total cost = $2.5
